Taking a 5000 mile journey from Chicago to San Francisco, to Las Vegas, and back....(everywhere in-between too), I tracked fuel consumption very closely. Here were the influential factors.
- 2007 Phoenix Cruiser, Model 2350, E350 Chassis, V10 Gas Engine
- Towing a small car 100% of the time
- 10 hours of generator usage, using the same fuel from the same gas tank
- exceeded "towing restricted" speed limits by 5mph; top speed varied pending a variety of state towing speed limits
- used cruise control 50% of the miles driven; cruise control is bad for fuel economy
We averaged 9.5mpg
